Webinar: How GLPs Enhance the Quality of Regulated and Non-Regulated Toxicology

October 18, 2016
This one-hour webinar, led by IIVS Director of Quality and Compliance, introduces some of the concepts of Good Laboratory Practices (GLPs) designed to promote study and data integrity within an in vitro toxicology framework. Applying these concepts within your own laboratory should aid in production of robust, repeatable studies. View Slides...

Cytosensor Microphysiometer

August 24, 2016
The Cytosensor Microphysiometer assay is an in vitro cellular toxicity test used to evaluate ocular irritancy. A microphysiometer is used to detect and monitor the extracellular changes in pH in L929 (mouse fibroblast) cells after exposure to a test material. Changes in the pH are caused by variations in the metabolic rate, measured indirectly as a function of changes in extracellular acidification. Metabolism in living cells is tightly coupled to cellular ATP usage and extracellular release of acidic byproducts such as protons, lactic...

Ocular Irritection (OIA)

August 24, 2016
The Ocular Irritection Assay is an in chemico eye irritation assay that detects, ranks, and predicts the corneal irritation potential of a test material. The assay assesses changes to the reagent solution (containing proteins, glycoproteins, lipids), which mimics the denaturation and disruption that occurs in corneal proteins in vivo. The test article is applied to a membrane disc that controls the delivery to the reagent solution. The changes in the protein structure are measured by optical density readings in the reagent...

Eye Irritation Test (EIT, OECD 492)

August 24, 2016
The Eye Irritation Test (EIT) is an OECD-approved in vitro non-animal test method for identifying chemicals and mixtures that may be irritating to the corneal epithelium.. The test method utilizes an in vitro reconstructed human corneal epithelium (RhCE) model (EpiOcular™, MatTek Corp.), in an acute exposure assay to support international regulatory labeling requirements, according to the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (UN GHS). The Eye Irritation Test can be used to support European Cosmetics dossier...
